Product Description

PI3EQX6741ST is a low power, signal SATA Gen 3i 6Gbps ReDriver. The device provides programmable equalization and output emphasis, to optimize performance over a variety of physical mediums by reducing Inter-Symbol Interference. PI3EQX6741ST supports two 100Ω Differential CML data I/O’s between the Protocol ASIC to a switch fabric, across a backplane, or to extend the signals across other distant data pathways on the user’s platform.

The integrated equalization circuitry provides flexibility with signal integrity of the signal before the ReDriver.

A low-level input signal detection and output squelch function is provided for each channel. Each channel operates fully independently. When the channels are enabled (EN=1) and operating, that channels input signal level (on xI+/-) determines whether the output is active. If the input signal level of the channel falls below the active threshold level (Vth) then the outputs are driven to the common mode voltage.

Termination Detect indication (TDet_A# or TDET_B#) provides indication when the load is connected ie HDD or Host. This can be used as control to go into power saving mode by either the host or HDD.

In addition to signal conditioning, when EN = 0, the device enters a low power standby mode.
